Overview
The TPS3703-Q1 device, specifically the TPS3703B3080DSERQ1 model, is an integrated overvoltage (OV) and undervoltage (UV) monitor or reset IC produced by Texas Instruments. It is packaged in the industry’s smallest 6-pin DSE (WSON) package, making it ideal for systems operating on low-voltage supply rails with narrow margin supply tolerances. This highly accurate voltage supervisor is designed to prevent false reset signals through low threshold hysteresis, internal glitch immunity, and noise filters. The device is AEC-Q100 qualified for automotive applications, with a temperature range of –40°C to +125°C, and is functional safety-capable.
